Abstract

A luminaire arrangement for providing a luminous flux in a target direction (z) comprising a light guide (101), multiple light sources (103) arranged at said light guide for emitting light into said light guide, out coupling means (106) arranged at said light guide and adapted to direct light out from said light guide; and a cover layer (102) arranged in front of said light guide at the side where light it to be directed out, said cover layer being provided with at least one optically transparent area (104) such that light directed out from said light guide is allowed to pass said cover layer. The cover layer allows for use of the same or similar light guide, light sources and out coupling means in a number of different luminaire applications, where each application may have different requirements on e.g. appearance, and/or collimation and/or directivity of the luminous flux.
